Motors MX-4070

[RascalMJ]

We are seeing an issue here with the following motors: See attached picture. I can certainly take more pictures if needed. The 3 motors in the picture were from 1 system with under 50k total (approx 34k black and 12k color). Various error codes depending on which motor actually fails first.

RMOTP1068FCPZ - Process motor BK
RMOTP1063FCPZ - Process motor


I have seen this issue on 3 different MX-4070N systems. These motors fail with the gear being stripped away. One of these systems only had approx 20k on it before the motor failed. Typically it is one motor that fails before the others, but the other 2 are close behind. We learned to check all three now. Has anyone else seen this issue? Perhaps a fix? Thanks as always for any assistance.

Re: Motors MX-4070

we also are having the same issue doesn't make sense sense they ride against plastic gears how does metal wear out before plastic. We changed the whole drive unit and motors and so far so good.

YES!!!! That is what I am saying!

We were replacing just the motors thinking it was a "one off" kind of thing and were monitoring it. Then we had one of them backordered and couldn't get it, so I looked into getting the whole drive unit to try that. I did it once and have been keeping an eye on it, but they have only run about 10k since I installed it.

Thanks for your response. I was feeling out on an island on this one! Nothing on here or service bulletins ....etc. Usually I can wait it out, or find enough answers before I have to create a thread. hahah

Re: Motors MX-4070

I have had this on at least 5 of the new machines (3070-4070) and various other models.
It boils down to a crap design.
The previous models had a motor for each color, four motors, four colors. The new machines have a motor for black and ONE motor for all three colors. Only 1 motor running all three drums amd DV is too much, thus those motors strip. We had this on a desktop c300 a few weeks back and it was the same crap design.
I had a 4070 that did this motor stripping twice and the main drive motor had to be replaced.

Additionally, this crap design is made worse by not only clogged toner tubes and hoppers (F2-6x & F2-7x codes), but also drum unit with seizing augers.
It cant drive a normal amount of toner in the three DV boxes, imagine the increased load when the DV tanks are over stuffed with toner.

Re: Motors MX-4070

I dug out some more documentation on this issue. The link at the bottom links to the photos but there are a few common symptoms this issue will create.

1. F2-6x codes with the toner cart ejected from the machine. Anytime I see the toner peaking out, I check for no drive or a clogged tube / hopper. You can also use SIM 10-2 to check the hopper sensors (5070-6070) for clogs. The sensor that does not change states is clogged and will have to be purged or removed and cleaned out. 3070-4070 do not have these sensors.
2. DV entrance ports are filled the the rim. In the photos, you can see how all three color DV units are crammed full of toner. You can also see the stalled toner clustered at the rear.
3. Horrible noise when color copying or printing. I have had techs go in and run BW prints and close the call having never tested the color side. SIM 25-1 ensures all items are run and tested; believe me, you cant miss that noise.

Hope this helps



EDIT: disregard that bright magenta blob in photo 9. Has nothing to do with this post, but believe it or not there IS a developer unit under there.

Wow, we haven't seen any that bad. We have had a couple DV units show the symptom above, but were able to clear them out and move along. Thanks for the info though, seems any info will be solid at this point until something gets figured out. I have never had to even look at one of those types of motors previously, not I am getting good at replacing them. ha

Re: Motors MX-4070

Just had two of these last week.

All three motors mentioned, show signs of wear, but motor that failed in both cases is color dv motor.

Both machines extremely low copy count.....only thing they have in common is their location.....both deliveries were an hour plus away and were delivered with toner and dv units in place.

Was just curious if this may be the cause

Re: Motors MX-4070

It seems there will be a rash of customer complaints to Sharp very soon.

Re: Motors MX-4070

We have had 1 main motor replacement and 10 motor replacement, 9 of 10 being color.

Re: Motors MX-4070

You might try Kyocera part number: M014600050 FLOIL G2-Z55 50G

We saw this same exact problem on the Kyocera Harrier series fuser drive unit. There was some changing of gears and motors, but I think the biggest difference was the lubricant. Many techs replaced drive assemblies and saw improvement. I changed the worn gears and motor, cleaned all the gear teeth with toothbrush and orange oil solvent, then lubricated the gear teeth with this FLOIL. Huge improvement.

FLOIL G2-Z55 50G

Part of me making this post is just now having a little time and NEED to flush out all the details. My thoughts too were lubricant, but I wasn't sure what type might be best (least likely to make worse. ha)

I will certainly look into your recommendation. THANKS

Re: Motors MX-4070

I had a noisy MX3050n with dev drive issues that needed the Main Drive Assembly, and all was well after replacing it.

5 months down the road the same machine was jamming and making a weird noise. Apparently the motor that drive the Transport Assembly was worn at the spiral gear just the same.

Sharp is out if stock on this motor and gonna try CPLTM8993DS51 Transport Drive Motor Assembly that includes the motor in question.

Here's my pics :

Yep, we've had to order the assembly as well... I can't believe there isn't something "official" about this yet.

Re: Motors MX-4070

I pulled the paper feed motor (just above the transport motor), same part number, and there is wear on the gear in the same area where it meshes with the next gear. So looks like that one will be next. If that happens, that will make 3 major drive assemblies in one machine. 38K blk and 22K clr.

Biggest pieces of crap since the SF-2020 days...garbage.
